The Special 45th Anniversary Edition HKS Super Turbo Twin Tail Titanium Cat-Back Exhaust for the 15+ Subaru WRX & 15+ Subaru WRX STi is a high performance exhaust system for those with discerning taste. It uses the extremely popular Super Turbo design but is made from 100% Titanium alloy for an extremely light system.

The Super Turbo Muffler combines a low back pressure design for improved power and torque but maintains low sound levels at low RPMs for comfortable street driving. This titanium variant cuts the weight of the exhaust system by 50% (when compared to OEM) but still implements the dual exit quad tip design. In order to make it more exclusive, HKS is only making 45 exhaust systems world wide to celebrate their 45th Year Anniversary.
